Turns out massive caches are good for more than games. House of Zen boasts 5-13% perf boost over prior-gen part

AMD aims to extend its lead in desktop gaming with a new CPU, dubbed the Ryzen 9 9950X3D2 Dual Edition. This top-of-the-line part has 16 cores fed by an absolutely massive 208 MB pool of cache, with memory spread across both CCDs.

The hotly anticipated processor chip is essentially a modified version of the 9950X3D announced in 2025, only both of the chip's two compute dies are now equipped with a 64 MB SRAM tile, boosting the L3 cache from 128 MB to 192 MB.

Larger caches benefit data heavy workloads, in particular PC games, by keeping more of the working memory closer to the cores. Since the launch of the Ryzen 7 5800X3D in 2022, AMD has used advanced packing to expand its chips' L3 cache without needing to design a larger die. This technology helped AMD to overtake long-time rival Intel in gaming CPU performance.
